I’m reluctant to push a non-pre-release gem that depends on a beta. Happy to bump the `twitter` dependency on `http_parser.rb` to ~> 0.6 once `0.6.0` final is released.

@tmm1 What’s standing in the way of a 0.6.0 release of `http_parser.rb`? It looks like there are currently [12 open issues](https://github.com/tmm1/http_parser.rb/issues?page=1&state=open). Which, if any, of these are blockers? What can we do to help push this release forward? It looks like the last beta was cut 6 months ago.
